It does not really have anything to do with size and everything to do with how EU and many European governments laws regarding what the cell companies have to do and are allowed to do. It is cheap to use cells pretty much everywhere in the EU and many of the cell companies are EU wide which would actually compare rather well to the states. As usual Americans are being lied to

NetOnNet sales people do not know more about hardware than the average person does. Some of the people at technical support knows a bit but not much more Great place to buy stuff but do the research somewhere else.

Thing is if you have both the experience and the certs you earn a lot of money and at least in the IT consultant industry having certifications gives your company many advantages and access to partner programs that they want. Also if they have a partner program that is dependent on your certification they are likely to keep you in front of pretty much everyone else. I was often paid a lot higher than the bosses at the company was and much was thanks to my certifications.
Edit: You will most likely need one of the higher certifications for this though. Like an MCSE, MCT from MS or at least as CCNP from CISCO. With an CCIE you can more or less set your own salary though. It is one of the highest sought after educations within Networking.
An A+, Network+, MCP, CCNA and so on will not do this for your career though. It has to be one of the higher Certification tracks out there.

From what I understand they are harder to take today. Back when they came out and I took Security+ it was at the level of what is SSL and why do you need a firewall Network+ was like MS Network Essentials light and A+ was also very easy. Passed all of them with no studying what so ever in the 90%+ score. CTT+ was harder since you had to do a video demonstrating teaching techniques and send it in.
If I were not retired today I would so go for the CCIE! I love the idea of doing a lab exam.

If he had sold it as is it would have been ok but he sold it as working. I think pretty much everyone I know would demand a refund even after more time than that. Might be because of consumer laws in Sweden though.

A definition of what you mean by a modem, coaxial, fiber and Ethernet is so needed here As you describe it what you need is a router. But then all of a sudden you link to a dsl modem? I am so lost as to what you are talking about
